Helpful Mum1,344This is a circle of people who are frequent G+ users. Really interesting to add if you are just getting started out. Feel free to share the circle.2014-05-18 18:35:454929511
Graeme McRae25,726Graeme's Circle of Active GooglePlussers! . . . This is a curated circle of active people on Google+ If you add this circle, you will see hundreds of new posts per day in your stream from this circle alone. If you’re in the circle (you’ll know ‘cause I notified you) then please reshare it! It's a circle of people I started following a few months ago, and who have consistently posted something at least once a week during all of weeks since then. If you want an interesting stream, you should add this circle. If you're interested in how I curated this circle, and why I think it makes for a really great stream, read on. . .How did these people get in the circle?. . . They must have posted something interesting, at least once, because I don't follow people unless they post something interesting. By now, you're probably not surprised by the number of people on G+ whose pages are full of repeated posts, videos without comments, "what's up" and other uninteresting things. I don't follow those people.How did they stay in the circle since they were added?. . . After I add someone, I keep them in the circle of people I added around the same time. Then, several times a week, I go through all my circles and delete people who haven't posted (something visible to me) in the last 7 days. So the people who are left in the circle are consistent posters. That says something important about them, because consistency is a proxy for quality.Wait. What? Why is consistency is a proxy for quality?. . . I'll admit it: I don't have the science to back up that wild statement, but I'll tell you why I believe it to be true. People who post crap don't get a lot of followers, and the few followers they have don't bother to engage. After a while, the crappy-posting people start to think G+ is a ghost town, and they lose interest. On the other hand, the people who share (or re-share) interesting things get followers and engagement, slowly at first, but ever increasing, and this outpouring of love is what keeps them going. That's what I think anyway, and I'm sticking to it.People who share interesting things get lots of followers. . . This is another half-baked theory of mine, but hear me out. You might think this makes sense: Google+ offers suggestions of people to follow, especially to new users. Google+'s only source of names to suggest are other G+ers like yourself. The G+ers who have the most engagement are the ones Google+ knows will be good to follow, so these people get put out as suggestions more often, and some percentage of those suggestions are taken up. So the more engagement you have, the more Google+ will suggest you as a person to follow, and so the more followers you'll get. Completing the theory: the more interesting the stuff you share (or reshare), the more engagement you'll get, and hence the more followers you'll get.How can I get in your circle?. . . Don't bother trying to "get into" this circle. This circle isn't for you to get into. Think of it the other way around. This circle is for you to add, so you can follow a bunch of interesting and consistent people. The stream from this one circle will be chock-full of fascinating content for you to reshare. People will start to notice your reshares, and they will engage with you, and then Google+ will "notice" (it's a computer, but let's anthropomorphise, shall we?) you and suggest you to others, who will then follow you.No, really. How can I get in your circle?. . . First, unfollow me, then wait, oh, about a week. Spend that week posting a shitload of interesting things. Then follow me. Since you're so interesting, Google+ will notify me that you followed me (G+ doesn'2014-05-17 08:06:51492564989

Bobo Fett4Those of you flocking here from the horror that is Facebook, or any that have been here for a while, or maybe even never a part of FB, some pointers to get you started.First thing to know if you type a question mark pretty much anywhere (as long as you don't have a text field in focus, in other words a blinking cursor where you would type text) in G+ you get a little pop up that gives you some handy basic keyboard shortcuts.If you are new here and and you are looking to make your feed more active, click the two little circles labeled Find people in the icons down the left side of the G+ page.  There you can search for people you know and add them to your circles.  Circles are what G+ uses to allow you to organize your friends list.  G+ starts you off with a few default Circles to use, you just need to add people and/or pages to things you enjoy to one of those circles.  Once you have you will see grey buttons at the top of your main feed (The page you get to if you click the big Google+ icon in the top left hand corner).  The first button is the default All circles button, here you will see all of the posts of every person/page you have added to any of your circles.  Next to the All button you will see buttons with the names of your circles.  If you click one of them you will of course see just posts from people/pages in that circle, but also on the rightish side, not quite at the top of the page, you will find a button that says Settings.  That is a drop down that gives you two check boxes.  One is "Show posts in home stream" the other is "Get Notified of new posts".  They pretty much do what they say, and "get notified" means any posts from this circle will make the number between your name and the + Share button in the top right hand corner increment and go red.  You can click that number at any time (even if it's red and 0) to get a drop down window which will show a condensed version of all posts from circles you get notified about. It will also notify you any time someone circles you back, and any +1s you have received in posts or comments you have made. As well as, comments in posts you have also commented on. On this Settings button you will also see a grey area that says Amount.  If you hover over that you get to choose More, Standard, or Fewer.  Which controls how frequently the posts from that circle appear in your feed.If you combine the above tools with the fact that you can change the name of any circle, add as many as you like, and also have people in more than one circle, you have very granular control over what posts you see and when, and exactly who can see your posts.  You can also share your circles with other people, as I have done below.  If you click the View shared circle button below, you will be able to see all the pages in a circle I call, go figure, Pages.  You can look through it and if you like everything you can just add the whole circle as a new circle.  Or, you can pick and choose which things you find interesting and add just them to your own circle that you already have or create a new circle.  Moving stuff from circle to circle is as easy and dragging the rectangle for that particular page/person and dropping onto the circle you want it to be in.  You could also just add this circle in full and then just delete the stuff you don't want (little x in top right hand corner of each rectangle when you hover over it).  Or just view this circle to get ideas for what sort of stuff can be searched for, and use the search box at the top of the Find people/Circle page to find stuff you like.Now once you have some friends added to circles, and pages/people you would like to follow added as well, your feed will get much more interesting. Now on to posting your own stuff.  In the Share what's new... field at the top of pages, you can of course type anything you like2013-05-03 19:55:12143001

You can also suggest people for this circle.Well, let's try something new here...When you start at Google+, you get a couple of default circles, and when I think back, I had no clue what to do with it. I read a lot of tuts about circle management etc. Started over a few times (bad habit), but it didn’t really worked out for me.I tried to get a number of people interested in Google+ by demonstrating it on the screen. I noticed how confused they were.So I started over with my circle management again, now with a different approach. I took all my interests in my daily live, converted them into interest circles. When I demonstrate Google+ to people now, I don’t see those confused looks anymore, must done something right here.Most Google+ users keep there circle management for themselves (I noticed). I’m going to do the opposite here, I’m gonna share more than 40 interest circles, handpicked (except the Galaxy Nexus circle and the Chromebook circle, these are started by others shared circles).2012-02-28 22:11:3383221

Chris Robinson14,511Science in a CircleA circle is a simple shape of Euclidean geometry consisting of those points in a plane that are a given distance from a given point, the centre. The distance between any of the points and the centre is called the radius. The word "circle" derives from the Greek, kirkos "a circle," from the base ker- which means to turn or bend. The origins of the words "circus" and "circuit" are closely related. The circle has been known since before the beginning of recorded history. Natural circles would have been observed, such as the Moon, Sun, and a short plant stalk blowing in the wind on sand, which forms a circle shape in the sand. The circle is the basis for the wheel, which, with related inventions such as gears, makes much of modern civilisation possible. In mathematics, the study of the circle has helped inspire the development of geometry, astronomy, and calculus. Excerpt taken from: http://goo.gl/P21YC.Here on Google+ circle has a different meaning. It's a powerful tool for categorizing profiles and pages. Circles can be beautiful and informative, especially when they're filled with science! I am sharing 50 pages that actively disseminate scientific material; however, it would be nice to build up this circle, as well as the scientific community more generally. Please comment on the original post (http://goo.gl/V1VyI) if you know of other high quality science pages on Google+.

Study Links Physical Activity in Older Adults to Brain White Matter Integrity

Full article at http://neurosciencenews.com/white-matter-aging-activity-neuroscience-1334.

Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity – not just the degree to which he or she engaged in moderate or vigorous exercise, but also whether the person was sedentary the rest of the time.

The research is in PLOS ONE. (full open access)

Overindulging in high-calorie snacks is partly caused by lapses in a very specific part of the brain, according to a new University of Waterloo study.

The research is in Psychosomatic Medicine: Journal of Biobehavioral Medicine. (full open access)

Research: “The Effects of Continuous Theta Burst Stimulation to the Left Dorsolateral Prefrontal Cortex on Executive Function, Food Cravings, and Snack Food Consumption” by Lowe, Cassandra J. MSc; Hall, Peter A. PhD; Staines, and William R. PhD in Psychosomatic Medicine: Journal of Biobehavioral Medicine. doi:10.1097/PSY.0000000000000090

Image: The study used continuous theta burst stimulation, a form of transcranial magnetic stimulation, to temporarily reduce activity in participants’ left dorsolateral cortex. After receiving theta burst stimulation, participants not only reported greater food cravings for calorie-dense food, but ate more junk food during a taste test than when they received a bogus stimulation.

Evidence of Genetic Link to PTSD in Soldiers Exposed to Childhood Trauma

Full article at http://neurosciencenews.com/genetics-ptsd-childhood-trauma-1330.

While abnormalities in the adrenergic and noradrenergic systems, both integral in the fight-or-flight response, are thought to play a role in the development of post-traumatic stress disorder (PTSD), until now there has been no genetic evidence of this connection. A collaborative study just released by researchers at Columbia University’s Mailman School of Public Health and the University of Michigan found an interaction between the ADRB2 gene and childhood adversity.

EEG Study Findings Reveal How Fear is Processed in the Brain

Full article at http://neurosciencenews.com/eeg-ptsd-images-psychology-1325.

New research from the Center for BrainHealth at The University of Texas at Dallas published online today in Brain and Cognition illustrates how fear arises in the brain when individuals are exposed to threatening images. This novel study is the first to separate emotion from threat by controlling for the dimension of arousal, the emotional reaction provoked, whether positive or negative, in response to stimuli. Building on previous animal and human research, the study identifies an electrophysiological marker for threat in the brain.

Image: The scheme demonstrating how an MPF map is computed from source MR images. Imaging protocol includes three gradient-echo images with variable flip angles, a gradient-echo image with off-resonance radiofrequency saturation enabling the magnetization transfer effect (MT-weighted image), and a reference image that is a similar gradient-echo image obtained without saturation. Additionally, an MR imager produces maps of the main magnetic field (B0) and radiofrequency field (B1), which are used to correct errors caused by imperfectness of imager’s hardware. MPF maps are computed voxel-by-voxel in two steps, (A) and (B), using special software developed by the authors. During the first step (A), a map of the longitudinal relaxation rate (R1) is generated as described in the literature. This map along with an MT-weighted image and a reference image are used to compute an MPF map in the second step (B) based on an iterative algorithm recently described by the authors.

Image: The researchers found that the NAP structure allows it to bind to the tip of the growing microtubule, the emerging “railway,” through specific microtubule end-binding proteins, which adhere to microtubules a bit like locomotors to provide for growth and forward movement, while the other end of the microtubule may to be disintegrating. These growing tips enlist regulatory proteins that are essential for providing plasticity at the nerve cell connection points, the synapses.

Were Albert Einstein and Leonardo da Vinci born brilliant or did they acquire their intelligence through effort?

No one knows for sure, but telling people the latter – that hard work trumps genes – causes instant changes in the brain and may make them more willing to strive for success, indicates a new study from Michigan State University.
